Motor packages include the motors, igniters, and plugs to install the
igniter easily with. Bulk packages also include recovery wadding. Be
sure to always have a spare pack of model rocket recovery wadding
since it is specially made to prevent ground fires and also be biodegradable.
It's not just toilet paper. It's toilet paper impregnated with
fire retardant chemical borax protecting your launch site, parachute, and your rocket.

We sell Estes brand motors with a minimum $40 order and a flat
$8 shipping charge by ground anywhere in the continental United States.
Kits alone have a minimum $8 flat shipping charge.
You may place an order by email.

As with all U.S. Rockets kits, any length motor may be used due to the
use of an ingenious method of motor installation. A paper tape or masking tape thrust
ring is wrapped on the nozzle end of the motor and once in place, the
motor is held in place by a band of tape over the thrust ring and motor
mount tube end. Fly big, fly high, fly fast, but above all, please fly safely.

U.S. Rockets rocket kitsrequires assembly and can be painted and reflown.

U.S. Rockets Weightlofter and Banshee rocket kits ready for flight!

U.S. Rockets Miniroc 1.2 single stage and MR 2B two stage rocket kits.
The Miniroc 1.2 has a 29mm host mount for E-H motors and the included
24mm conversion accepts C-G motors. The MR 2B has fixed 18mm mounts
for a variety of standard 18mm motor combinations such as A8-0/A8-5,
B6-0/B6-6 or C6-0/C6-7. Don't forget a piston booster using PLMSPK.

U.S. Rockets offers Interchange Mounts-tm to fit
13mm in 18mm, 18mm in 24mm, 24mm in 29mm and
3 x 13mm in 29mm, 3 x 18mm in 38mm, 3 x 24mm in 54mm,
and others. Many kits include Interchange Mounts-tm
which can be used in any other rocket as well.

13mm typically includes motor powers from 1/4A to A,
including 1/4A, 1/2A and A, with each one involving a
doubling of power from the prior.

18mm diameter
motors includes 1/2A, A, B and C.

24mm includes C, D and E in Black Powder
propellant motors such as Estes and can include D, E, F
and G using over 2x as powerful Ammonium Perchlorate
Composite Propellant (APCP) such as some from U.S. Rockets.

There are
also larger diameters of motors that require a free
FAA waiver to fly including 29mm E-J, 38mm H-K and
54mm H-M. A midrange power
H motor is the maximum FAA exempt power.
Since each letter represents a doubling of power,
an F is 8x the power of a B and an I is 64x the power
of a B motor. A motor with D power has 2x the propellant
weight of BP vs. APCP but the power is the same.

Within
a certain power, different motors can have different
burning times, to make the flight faster or slower.
Different weight rockets need different coasting delay
times to have the recovery system deploy near apogee
when the flight is slowest and the stresses are lowest.

A wide variety of U.S. Rockets kits are
directly compatible with Estes motors.
